TPSM53602

The TPSM53602 power module is a highly integrated 2-A power solution that combines a 36-V input, stepdown, DC/DC converter with power MOSFETs, a shielded inductor, and passives in a thermallyenhanced QFN package. The 5-mm x 5.5-mm x 4mm, 15-pin package uses Enhanced HotRod QFN technology for improved thermal performance, small footprint, and low EMI. The package footprint has all pins accessible from the perimeter and a single large thermal pad for simple layout and easy handling in manufacturing.

The total solution requires as few as four external and magnetics part selection from the design process.

• (3) The ambient temperature is the air temperature of the surrounding environment. The junction temperature is the temperature of the internal power IC when the device is powered. Operating below the maximum ambient temperature, as shown in the safe operating area (SOA) curves in the typical characteristics sections, ensures that the maximum junction temperature of any component inside the module is never exceeded.

The TPSM53602 is a synchronous, step-down, DC/DC power module. It is used to convert a higher DC voltage to a lower DC voltage with a maximum output current of 2 A. The TPSM53602 can be configured in a negative output voltage, inverting buck-boost (IBB) topology. For more details, see the Negative Output Voltage using the TPSM53602/3/4 application note. The following design procedure can be used to select components for the TPSM53602. Alternately, the WEBENCH ® software can be used to generate complete designs. When generating a design, the WEBENCH ® software uses an iterative design procedure and accesses comprehensive databases of components. See www.ti.com for more details.
